Introducing the Interchange™
Interchange allows remote access to your party line intercom through select
JK Audio POTS and VoIP phone hybrids. This professional half rack interface
provides a four wire audio interface and remote control connection for JK Audio
innkeeper LTD, innkeeper 1x/1rx™, or innkeeper 2™ Digital Hybrids for POTS
lines. Likewise, couple a JK Audio PBXport™ with an Interchange™ for PBX/
VoIP lines, or connect a JK Audio AutoHybrid IP2™ for VoIP or AoIP connections.
The front panel headset interface jack allows easy connection of your mobile
phone, tablet, or computer allowing remote access through a wireless phone or
conferencing app.
Interchange contains a sophisticated intercom hybrid in a low noise pro audio
design. The Listen-Always design allows both the phone hybrid / 4-wire
connection and the mobile phone headset interface to monitor the intercom just
like any other belt pack. Listen mode is a high impedance bridging tap on the
intercom line. Talk mode is enabled via a front panel switch, either Off, On, or
Auto. Auto follows the phone hybrid Auto-Answer mode. Talk mode uses a solid
state relay to properly couple Talk audio from the phone line and mobile phone
interfaces, to the intercom channel.
The Innkeeper 2 and AutoHybrid IP2 conference features allows two callers to
share one intercom connection. Alternatively, the included cables allow Line 1
and Line 2 of the Innkeeper 2 or AutoHybrid IP2 to be connected to two separate
Interchange units, allowing connection to separate intercom loops.
